A series of 22 novel 1,2-disubstituted-1H-benzimidazole-N-alkylated-5- carboxamidine derivatives were synthesized and evaluated for in vitro antibacterial activity against S. aureus and methicillin resistant S. aureus (MRSA), E. coli, E. faecalis and for antifungal activity against C. albicans. Compound 59 [1-(2,4-dichlorobenzyl)-N- (2-diethylaminoethyl)-1H-benzimidazole-5-carboxamidine], with a 3
合成了一系列 22 种新型 1,2-二取代-1H-苯并咪唑-N-烷基化-5-甲脒衍生物,并评估其对金黄色葡萄球菌和耐甲氧西林金黄色葡萄球菌 (MRSA)、大肠杆菌、 E. faecalis 和针对白色念珠菌的抗真菌活性。化合物 59 [1-(2,4-二氯苄基)-N-(2-二乙氨基乙基)-1H-苯并咪唑-5-甲脒],在 C-2 位具有 3,4-二氯苯基,显示出最大的活性( MIC = 3.12 microg/mL 对抗某些细菌和真菌白色念珠菌)。

The design and synthesis of compounds that target mixed, AT/GC, DNAsequences is described. The design concept connects two N-methyl-benzimidazole-thiophene single GC recognition units with a flexible linker that lets the compound fit the shape and twist of the DNAminorgroove while covering a full turn of the double helix.

A series of 28 novel 1,2-disubstituted-1H-benzimidazole-N-alkylated-5-carboxamidine derivatives were synthesized and evaluated for in vitro antibacterial activities against Staphylococcus aureus and methicillin resistant S. aureus (MRSA) by the tube dilution method. The results showed that compounds 45-46 and 55-57, having 3,4-dichloro substituted phenyl at the position C-2, of N-bulky alkyl substituted benzimidazolecarboxamidines exhibited the greatest activity with MIC values of 1.56-0.39 mu g/ml.
